The iQx measures air temperature and velocity, surface temperature, air pressure drop and humidity. Measurements can be made concurrently or individually.

The design allows airflow to be measured and controlled at a single station, making it suited for applications requiring air balance to ±5 percent (in a straight duct) on a regular basis.

Series ST50 provides precise measurement of airflow and natural gas to operate batch systems more efficiently while improving end-product quality and reducing energy costs, says the manufacturer. 

No. 859 is designed for drying powdered resin in trays. Workspace dimensions of the 550°F (288°C) shelf oven measure 44 x 30 x 60”, and 12 KW are installed in Nichrome wire heating elements.

Blue M industrial ovens have temperature ranges of 27°F (15°C) above ambient to 662°F (350°C). They are designed with semi-perforated walls that allow for tuning of the oven airflow to maximize heating rates and uniformity.

It’s a point of pride that I have every issue of Process Heating ever published cataloged in a small library in my home office. Admittedly, it’s not as tidy as you might find at your local library. I tend to stack issues that I “check out” on the floor in front of the library until it’s time to clean my office. And, while my lazy filing means a career as a bibliophilic cataloger is doubtful, it also provides opportunities for rediscovery.

In an interview with Editor Linda Becker, Despatch Industries’ Rolf Kragseth shares further insights about drying products with solvent loads — the type of drying typically done in Class A ovens.

Drying applications vary: from drying frac sand — a relatively simply process often performed for screening purposes — to applications like drying wetted primer in ammunition — a process that depends on accurate temperatures sustained over time. Yet, in drying applications from simple to complex, airflow and temperature uniformity makes a difference.

Process cooling is the function of removing heat in order to control or maintain appropriate temperature levels. Almost every manufacturing process produces a certain amount of excess heat due to friction or process heating.

Model APK is are available in diameters from 12 through 36” with capacities ranging to 23,000 cfm.
